We created the Boltlock and released it at the Brooklyn Museum to celebrate their David Bowie exhibit. It wasn't a coincidence. Sizewise the lock is in between a Babylock and a Medium Lock. This Sterling Silver Boltlock measures 3cm x 10mm. Can be machine engraved

Our most popular heavy silver chain. The chain has an old style Victorian feel because we oxidize the silver to give it that old quality. The gold loops turn a simple silver chain into something truly spectacular. Sterling silver chain with 14k gold loops. The links each measure about 4.6mm X 5.5mm.
